There is a famous quote attributed to then-Cardinal Joseph Ratzinger in 1997, in comments to a Bavarian television station. The future Pope Benedict XVI said the Holy Spirit acted like a good educator in a conclave, allowing cardinals to freely choose a pope without dictating the precise candidate.

Beyond simply picking who the next pope will be, players and gamblers also can guess how many tries it will take the cardinals to choose the leader, which day of the week he’ll be elected, what new name he will decide on, or where his priorities will land on the progressive-conservative scale.
